Steve Loughran updated HADOOP-13531: ------------------------------------ Resolution: Duplicate Status: Resolved (was: Patch Available) > S3A output streams to share a single LocalDirAllocator for round-robin drive > use > -------------------------------------------------------------------------------- > > Key: HADOOP-13531 > URL: https://issues.apache.org/jira/browse/HADOOP-13531 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Affects Versions: 2.8.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Minor > Attachments: HADOOP-13531-001.patch > > > {{S3AOutputStream}} uses {{LocalDirAllocator}} to choose a directory from the > comma-separated list of buffers —but it creates a new instance for every > output stream. This misses a key point of the allocator: for it to do > round-robin allocation, it needs to remember the last disk written to. If a > new instance is used for every file: no history. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
